About Ladders
Ladders are devices that workers use to step up or gain access to elevated surfaces. There are several basic types of ladders, including rope ladders and rigid ladders. Rigid ladders can be step ladders, extension ladders, telescoping ladders, roof ladders, and hook ladders. Extension ladders are divided into two or more lengths for convenient storage and transportation, and so that the ladder can be lengthened for use. A pulley system can allow the ladder can be easily extended by an operator on the ground. Rolling ladders are mounted on wheels or casters so that workers can easily move the ladders into place. Marine ladders and dock ladders are made from materials that can resist corrosion, such as stainless steel or anodized aluminum.
